UCS Hyperflex Trunk-servicelevering en -verificatie

Inleiding

In dit document wordt ZooKeeper beschreven, wat in wezen een gecentraliseerde service is voor gedistribueerde systemen naar een hiërarchische waardeopslag. Het wordt gebruikt om een gedistribueerde configuratie service, synchronisatieservice en naamgeving voor grote gedistribueerde systemen te bieden. De architectuur van ZooKeeper ondersteunt hoge beschikbaarheid door redundante services. Clients kunnen dus een andere ZooKeeper-leider vragen als de eerste geen antwoord geeft. ZooKeeper-knooppunten slaan hun gegevens op in een hiërarchische naamruimte, zoals een bestandssysteem of een boomgegevensstructuur. Clients kunnen lezen en schrijven naar de knooppunten en hebben zo een gedeelde configuratiedienst. ZooKeeper kan worden gezien als een atomisch uitgezonden systeem waardoor updates volledig geordend zijn.

ZooKeeper biedt deze belangrijkste functies:

• Betrouwbaar systeem - Het systeem is zeer betrouwbaar omdat het blijft werken, zelfs wanneer een knooppunt niet werkt.
• Eenvoudige architectuur - De architectuur van ZooKeeper is vrij eenvoudig; het gebruikt een gedeelde hiërarchische naamruimte , die helpt bij de procescoördinatie .
• Snel verwerken - ZooKeeper is vooral snel voor lezen-dominante werklasten.
• Schaalbaar - De prestaties van ZooKeeper kunnen worden verbeterd door het toevoegen van knooppunten.

In HX is er deze specifieke implementatie:

• De service die exposant heet, beheert zooetueper startup/shutdown.
• Processen binnen de HX-cluster zijn klanten aan Zookeeper en communiceren via tcp poort 2181 ex storfs, stmgr, enzovoort.
• Systemen met meer dan vijf knooppunten zullen een aantal knooppunten in de stand-alone hebben. Systemen met vijf knooppunten of minder zouden nooit een knooppunt in een stand-alone moeten hebben.
• Het minimumaantal knooppunten vereist voor Quorum = N/2 +1.

Bijvoorbeeld, voor een drieknoopcluster - N/2=1.5 Rond naar 1 +1 =2 (slechts één noedelstoring kan worden getolereerd)

Bijvoorbeeld voor een vijf knooppunt-cluster - N/2=2.5 Rond naar 2 +1 =3 (er kunnen slechts twee knooppunten worden getolereerd)

Aangezien u slechts vijf knooppunten voor een ZK-cluster doet, tolereer u slechts een maximum van twee knooppunten voor om het even welk aantal knopen in de cluster. Dit geldt voor geconvergeerde knooppunten.

Zoeker-service

Zoveel heeft een syntax van vier letters die je in staat stelt om de status van een zoekopdracht, lijstverbindingen, aantal knooppunten enzovoort weer te geven.

Controleer de dierentuinstatus op het lokale knooppunt - (ok ==> Gaat het?.. imok=>Ik ben OK).

root@SpringpathControllerMSH7NHXRFL:/var/log/zookeeper# echo ruok|nc localhost 2181
imok

Controleer of de dierentuin een leider of volger is.
